SimAVR is a lean, mean and hackable AVR simulator.
Warning
SimAVR does not work on Windows for the Unit Testing due to issue #489.
Integration of the SimAVR simulator requires adding the
platformio/tool-simavr
package to the platform_packages option in your
“platformio.ini” (Project Configuration File), setting test_speed to the 9600,
and overriding test_testing_command.
See the example of platformio.ini for the Arduino Uno
board from Atmel AVR:
[env:uno]
platform = atmelavr
framework = arduino
board = uno
platform_packages =
platformio/tool-simavr
test_speed = 9600
test_testing_command =
${platformio.packages_dir}/tool-simavr/bin/simavr
-m
atmega328p
-f
16000000L
${platformio.build_dir}/${this.__env__}/firmware.elf
SimAVR does not require a firmware uploading stage. Please use
the pio test --without-uploading command option.
> pio test --without-uploading
Verbose mode can be enabled via `-v, --verbose` option
